I have a flame-metalizing setup that I picked up perhaps ten years ago but have never used. It has a raft of different powdered metals/alloys from which to choose, depending on the specific application. It's basically an evaporative process which condenses/bonds to metal to build it back up to spec, same as the process you've described. Also similar to the "fume" work my son does in his glass-work.
